About the Project
The aim is to enhance the physicochemical properties of Active Pharmaceutical Ingredients (API) by generating novel physical complexes (in particular, co-crystals) containing API with improved physicochemical properties for drug delivery purposes. This will involve exploring the impact of a range of formulations (such as solutions/emulsions/microemulsions) containing API and suitable excipients for complex/co-crystal formation during the drying process. In addition, simple to complex drying processes (e.g. spray drying, freeze-drying, controlled crystallization etc.) will be used to produce powders with desired properties that will then be subject to characterisation. A range of characterisation methods will be used such as differential scanning calorimetry, x-ray powder diffraction, nuclear magnetic resonance and scanning electron microscopy. For in vitro assessment of deposition, the prepared formulations will be evaluated using a next generation impactor to simulate deposition in the lungs. The antibacterial activity will be assessed using Pseudomonas aeruginosa and biofilms with the aim of determining formulations that enhance antibacterial properties.
This research could lead to potential benefits, as follows:
• Novel technologies will be developed for the formulation of particles with enhanced physicochemical properties
• Improved understanding of particle engineering processes that could accelerate drug development programmes and expand industrial capabilities
• Improved antimicrobial activity of drugs
